The mining machine herein: lillustrated and to whichmydnventiom is applied is of. the. breast type, having a stationarypr frame and a movable frame supported upon cam-ying the cutters and the motor. lIt is in its. generalfeatures of; construction similar to-theminingfinachine illustrated in l Patenti 684,356 .to H.y B. -DierdoriL-.dated October 8, 1901, to which .patent reference is'ma'de for details of construction:

The ".main vor bed frameof the mining 4machine'consists essentially-'oi the side barsv 2,' the cross bars 3; of suitable number', and thev shoes {Lupon which'the. when in working4 posi-tionsl W'ithin 4this frame is mounted the movable Acutter frame,

on the' shaft a'v and there is proyideda gear wheel on the shaft 8 in position' to mesh with t is gear lwheel of the gearing 9 when the cutter frame' is yin its rear"position. Uponone end of this' shaft thereis Secured a sprocket or 'chain wheel 10 arranged to he` Vconnected by a chain or belt 11 with a wheel 12 upon one ofthe axlesof the supporting car or truck E. Through this train of mechanism the-truck isl propelled from thevmotor of the mining machine when thelatter is inplace' upon the car. There'are also secured `upon thecro'ss vshaft 8 a parof Winches 13, .one at either end ofthe shaft. 14, 14A are'grooved guide pulleys mounted upon vertically disposed supporting pins or studs-15, which in -tu'rn are carried by brackets 16. There 'is oneI of, these brackets at each side of the machine :and it is preferably supported upon and adjustable alongl a side bar 2 of the lmain frame.

17, 17 represent jacks or posts adapted to be secured-fin place in oneposition or al1- other'within the mineV chamber, and adapted to be easily set in place in whatever positions itmay be desirable they should occupy.

one end to one of the jacks or posts 17 and to be'wrapped around one of the Winches 13, passing in its course4 one of the grooved pulleys. 14, if this should be found desirable to give direction tothe rope and cause it to lWork' properly. A Y

With this Adescription, an understanding of the manner of working my invention' ma be had, reference being madeto vthe diagrammatic figure or view--Fig. 4.

In chamber A the ining machine is yrep'- resented as.' being/still supported upon-the truck, which has been run into-entry C, and close up tothe edge of the bench of the chamber. The first operations are to disconneet the motor .'from the driven axle of the truck B, which is usually done by removing the belt 11., and then to remove the mining machine from the truck, andfthis latter is .accomplished by properly setting two of the jacks or osts 17 and leading ropes therefrom to't e Winches. 13 upon the cross shaft 8. This having been done, the motor of the mining'machineis started and through the gearing 9 theshaft 8 'is rotated in proper direction to vwindup the rope and drag the and on tothe'floor or -bench of the mine chamben This will result in moving the miningv machine tomthe position indicated ml full'lmes in thev chamber A. It is next necessary' to move the'l'nachiney from this position to the position indicated'in'dotted vlilies in chamber AA where the first cut is to be` made; To secure this' movement of the machine, by means of its ow n motor, one Aof the jacks or posts 17 is set in' the corner of the mine chamber and a rope 18 is led therefrom past a guide pulley Manda to one o'f the Winches 13. The motor being started and theshaft rotated, the mining 'machine will be dragged diagonally'acrossthe chamsev bei' toward the position indicated in dotted lines. It may be p roperly set in working lposition by employing a vpair of ]acks or postsset as indicated, and two ropes 18, the

movement then vbeing similar to that which is indicated in the chamber A for hauling the machine off the truck.

`After'the first cut has been made, the machine is moved transversely across the' face of thef'wall of coal, the arrangement of jack and rope for 'this purpose being that indifhg machine will cated in the chamber A". be moved step by-'step from e/position indicated in full lines-inthi's chamberto that 'indicated in dotted lines, whichis. the position -of the final cut. The l'ast cut having been made, and it' being desiredto move the -machine back' to lposition fc1t`loading` upon the truck, the parts-are arranged as shown in chamberI 3.

It willbe understood "that the guide vpulleys *14' are adjusted from one`position to 1S indicates a rope adapted to bef secured at another as maybe required to cause the'machine to move in' the desired direction.

By means of the apparatus I havedescribed it is possible to easily shift a heavy mining machine from one position to ani methods to move it.

'other within a low chamber, where it would be exceedingly diiicult by the ordinary It will be observed that the rope-winding l and' guiding devices'vfor shifting the., mining' machine are located` upon the bed frame, so

that thestrains Vincident to shifting the ma- 'ching-as described, are taken thereby inthe first to provide in'a machine 'of this general character a cable guide which is`ad`Y gustable, to vary the line of draft. The ma-J chine shown is adapted 'onlyl for undercutlateral 1f tobr-.ng it into a new cutting poy eitiont What claim is i ting the coal heading, but it will be understood that my invention so far as -it involves the relatively movble cutting mechanism, is equally lllplicnole to any mining machine which comprises a main bed frame and a cutter frame movable bodily with res'pct thereto. 1 believe myself to have been the first to provide in a mining machine the combinationV of power means, on the machine for moving the cutter fect cutting, and poivermeans on the. machine for .moving the whole machine bodily in a .I'nining machine, the combination with a, relatively smooth bottomed bed frame adapted to rest directly upon the frame forward to ef- ,i

ground und to be freely moved in any direction, of a korf cutting mechanism on the bed frame operative when moved forward perpendicnlarly to .a coal face, a cable adapted to be anchored externally of the machine, and mechanism on the 'machine for engaging tbe cable to guide and wind it, the guiding parts of the said `mechanism being bodily movable along Ilines substantially parallel to the lines offorward movement of the cutting mechanism to permit adjustment of the line of draft.

Correction lh Letters Potent No. 1,215,692.

It is hereby oertiod that. in Letters Patent No. 1,215,692, granted February 13,

1917, upon the application of George B. Norris, of Columbus, Ollio, for an lmprovement. in Mining-Machines, un error appears requiring correction as follows: In

the heading to the primed specification and t-he headings to the two sheets of drawings, the date of filing the application should be December 18,.1905, instead of December 1s, 1915"; and om the ma Lerma Pme: should b'@ 'ma im :his

j.,m iel:t.ion therein' that the same may conform to the record of the case in the .Patent Office.
